Property Value

Type: Double
The coverage value of this result.

Remarks

The coverage value represents the fraction of points from the trained pattern that were found in the runtime vision data. It is a value between zero and one. It is a weighted ratio that divides the number of trained points that were matched in the runtime vision data by the total number of trained points in the pattern.

The score of a result is computed by multiplying the Clutter value of the result by the ClutterMultiplier and then subtracting that number from the result's Coverage value. The score increases as the coverage value rises, and typically decreases as the clutter value rises. The formula is:

Score = Coverage - (Clutter * ClutterMultiplier)

Notice that the score is never less than zero or greater than 1.0. It is always clipped to lie within this range.
